UNITED STATES PATENT orrron Specification of Letters Patent.

Patented Nov. 13, 1906.

Application filed March 12, 1906. Serial No. 305.631.

To all whom it may concern:

Be it known that I, JULrUs ADORJAN, a subject of the Emperor of Austria-Hungary, residing at Paris, in the Republic of France, have invented new and useful Improvements in Billiard-Cues, (for which a French patent has been filed February 20, 1906,) of which the following is a specification.

This invention relates to certain improvements in billiard-cues.

The present improvements enable the weight and position of the center of gravity of the cue to be varied within much wider limits than have heretofore been possible. To this end I provide the one with two or more cavities or recesses to receive masses of variable form and weight in order to obtain very considerable variations in the weight and in the position of the center of gravity, and in order that the invention may be readily understood I will describe it fully with reference to the annexed drawings, in which Figure 1 is a part-sectional elevation of a billiard-cue constructed in accordance with this invention. Figs. 2 and 3 are detail views showing two modes of mounting the additional weights within the cue. Figs. 4 and 5 are similar views showing two modes of constructing the said weights.

The billiard-cue, having its center of gravity at g, is divided on both sides of this point along the planes Y Z and V X and is then provided at opposite sides of the said point with cavities or recesses, such as 1 and 2, the open end of each of these cavities or recesses being furnished with a screw-thread, as 3 and 4, to engage with screws 5 and 6, with which the butt-end 7 and the forward part 8 of the one are provided.

The variations of the weight and the position of the center of gravity in a cue thus constructed are obtained by arranging within the aforesaid cavities or recesses bodies 9 of variable weight so mounted as to prevent any noise or rattling, and this in the following manner:

The heavy mass or weight 9 is of less diameter than that of the cavity or recess in which it is located, and said weight is kept in position by its two ends bearing against elastic packings whose purpose is to prevent noise. By screwing up the portion of the cue corresponding to the cavity or recess being dealt with pressure is exerted, thereby enabling the mass 9 to be held absolutely immovable by means of the plug or packing 10, of rubber or other elastic material. The arrangement of the mass or weight 9 in its cavity or recess may, furthermore, be eifected as shown, by way of example, in Figs. 2 and 3. It will thus be understood that by varying the nature of the heavy masses or weights or their sizes the weight! and center of gravity of the one can readily be varied. Thus in this way the forms shown in Figs. 4 and 5 can be given to the heavy mass or weightthat is to say,

by arranging on a rod 11 sleeves 12 and 13 of more or less heavy material. It will thus be readily understood that the heavy masses or weights being mounted in their cavities or recesses without touching the inner walls of this latter all noise is effectively and entirely obviated.

Obviously the number of cavities or recesses is not strictly limited to two, and any number thereof may be provided, in Which case the one would then consist of several sections screwed one into the other. Further, it is possible to provide only one cavity, the center of which will be at g and in which is established an adjustable weight, such as those which are shown, Figs. 4 and 5.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is

1. A billiard-cue having interior recesses, removable weights in said recesses and means for holding said weights at their ends only and so as to leave a space between the walls of the recesses and the weights.

2. A billiard-cue having interior recesses on both sides of its center of gravity, removable weights in said recesses, an elastic packing at one end of each recess against which one end of the weight bears, the other end of the weights bearing against the other end of the recess said weights being of less diameter than the recesses so that a space is left between the walls of the recess and the weights.

In-testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JULIUS ADORJAN.
